Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.

BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.

Enhanced method development capabilities with automated SPME extraction optimization

A workflow has been described enabling the automated selection of the most suitable extraction conditions (type of fiber, extraction time and temperature) for the GC/MS analysis of a number of contaminants in oil and water samples.
Applying the automated workflow described above the total time to identify the most suitable fiber and then optimize conditions was 4.5 days. Compared to performing the experiments manually which is estimated at 15 days this represents of time saving of 10 days.

Determining Carbohydrates in Essential and Non-essential Foodstuffs using Ion Chromatography

While carbohydrate determination of most foodstuffs requires only minimal sample preparation such as dilution and filtration, samples with interfering matrices such as protein-containing dairy products have to be dialysed before injection. This application note describes a straightforward ion chromatographic method to sensitively determine water-soluble polyols and sugar alcohols as well as mono-, di- and oligosaccharides.

Analysis of Fruit Commodities by GC-TOFMS and GCxGC-TOFMS Using QuEChERS Approach

The availability of fruit commodities from a wide variety of sources has increased the need for rapid and accurate screening for pesticides in fruit. Not all fruit commodities are brought to market under the strict guidelines of the United States Department of Agriculture. Determining whether or not the Environmental Protection Agency tolerances for various pesticides have been violated is important in the risk assessment for consumers in the United States.
